The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the menu for the next couple of weeks.
Right off the bat, we’re looking at a pretty quiet start. The first few days are a write-off, with nothing worthwhile to even mention. The real action doesn’t even start to stir until Saturday the 1st of August. There’s a gap of about a day and a half of flat, poor conditions at Jaconé before we get a look in.
Saturday, 1st August is where it starts to get interesting. We’ve got a solid pulse of 4ft SSE groundswell with a 12-second period rolling in. The wind is offshore from the NE, blowing at a gentle 15 mi/h. That’s going to leave the face clean and open. The combined swell energy is a moderate 441, so there’s a bit of push behind it. This is a proper standout for the region. The Saturday morning session at Jaconé is your best bet for a real surf. It’s a consistent, exposed break, so it’ll handle the swell well. Keep in mind, crowds are possible, so if you’re looking to get a few waves to yourself, you might have to work for it. Water temp is sitting at 72°, which is about average for this time of year.
Monday, 3rd August throws up another good one. The morning is looking glassy with a 4ft E swell, a short 7-second period, and glassy conditions from a NNE breeze at just 3 mi/h. That’s a morning of clean, fun waves. It’s not a big swell, so it’s a good option for all levels.
Moving into the second week, the forecast gets a bit more promising but also more uncertain. Monday, 10th August is a real standout for the experienced crew. We’re looking at a 7ft S swell with a very long 15-second period, pushing a huge combined energy of 1916. This is a lot of water moving. The wind is a light ESE cross-off. This is expert territory. That long-period groundswell will be powerful and will want to jack up. It’s best suited for a point or reef, but at Jaconé, a beach break, it might close out and be a real handful. The afternoon of the 10th and the morning of Tuesday, 11th August (another 7ft S swell) are the two biggest windows, but again, this is for the well-experienced only.
In summary: The best, most reliable surf on offer is the Saturday morning (1st August) at Jaconé with that clean 4ft SSE swell. Keep an eye on the 10th and 11th of August if you’re an expert looking for a real challenge, but be aware that long-period swell on a beach break can be tricky.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
